GERMANY APPARATUS FOR MOVING INGOTS OR MASfiES IN FURNACES Application filed. March 23, 1926, Serial No. 96,730, and in Germany May 23, 1925.

In order that ingots or slabs to be heated in furnaces may be uniformly heated, itis necessary to turn or to move them from time to time. Hitherto this has been done by hand in a cumbersome way or by apparatus built into the furnace. It will be understood, however, that these apparatuses are subjected to great wear, so that in practice it is preferred to turn or move the blocks by hand.

According to the invention a carriage is provided to run upon rails laid parallel to and in front of the furnace, the carriage being provided with a mechanically driven rod which is movable transversely to the furnace. The rails may be placed on the floor in front of the furnace, or they may be applied upon a suspended track. In the use of this apparatus, the rod is inserted into the furnace and pushed between two ingots. By moving the carriage along the rails, the ingots may be tilted and rolled. The movable rod may also be provided to oscillate in the horizontal plane upon the carriage in order that the ingots may be moved on the movement of the rod when the carriage is stationary. By means of such an apparatus several blocks can be moved together as desired, or they can be arranged singly and spaced out upon the track, but the track does not require to be inclined but may be disposed in the horizontal plane.

According to the invention, moreover, the apparatus is constructed in such manner that it can be used for turning angular in: gots and this is effected by shaping the forward end of the rod that is inserted into the furnace, in such manner that it engages the ingots underneath and also holds them at the sides, whereby the rod which may be inserted into the furnace and withdrawn therefrom has imparted to them both an axial and a radial movement.

For this purpose the rod is advantage ously provided circular in cross-section and is provided with teeth or ribs all round its periphery, so that the engagement of the pinion which operates the rod is maintained as the rod is turned. To rotate the rod it is advantageously provided with a toothed or Worm wheel, which carries the rod with it during working by means of a Wedge mounted in a longitudinal groove in the rod and turns the ingot held by it as is desired.

The drawings illustrate two constructions of apparatus according tothe invention by way of example;

Figure 1 is a plan of the apparatus according to the invention. 4

Figure 2 is an elevation corresponding to Figure 1, and

Figure 8 is an illustration of a part of the apparatus.

Figures 4, 5 and 6 are corresponding views of a constructional modification.

As illustrated in Figures 1 to 3, the travelling frame 1 runs upon the rails 2 of the heating or welding furnace 3, and it is provided with a toothed rod 4 which is circular in cross-section and which is moved forward and backward by means of the wormgear illustrated in the drawings, and by the pinion 6 and the motor 7 The-rod 4, together with the driving motor 7 and the base-part 8 oscillate in the horizontal plane. The base part 8 has mountedupon it a second motor 9, which drives a worm 11 by means of the toothed wheel and pinion 10, 10 The worm 11 engages with the worm wheel 12 and is mounted in bearings 13 on both sides of the rod 4; The worm wheel 12 (Figure 3) is slidably mounted on the rod 4 and is merely connected by one or more keys 13 with the rod 4. The key 13 is inserted in a longitudinal groove 14 in the rod-4, so

that the latter, without being affected by the driving gear 9, 10, 11, can be moved forward and backward. It will be understood that the rod 4 can be turned about its longitudinal axis by means of the driving The rod 4, which is supported upon the roller 15 and may be made hollow to enable it to be water-cooled, is provided at its for- "vention, but" the invention is not limited be moved about in the furnace so that the" best position may be secured for uniformlyheating the ingots. The angle part 15 may at the same time be provided for working upon the surface of the ingots and by this means the slag and'sinter adhering to the falling dust may be removed from the furnace ll I "l f ii g 1: 1

The motor 19 is provided for moving the whole apparatus along the rails. The rod 4:

with its driving gear is provided to move in using this apparatus, the rod is inserted into thefurna'ce after the door 20 has been raised, and isipushed between two contiguous sub- ,stantially cylindrical ingots- The ingots may, howfever, be moved-by swinging therod 4, Thus, -'in this manner very quick movements can be made, if desired.
